Phenotyping, Etiological Factors, and Biomarkers: Toward Precision Medicine in Autism Spectrum Disorders David Q
Special Article Phenotyping, Etiological Factors, and Biomarkers: Toward Precision Medicine in Autism Spectrum Disorders David Q. Beversdorf, MD; MISSOURI AUTISM SUMMIT CONSORTIUM* ABSTRACT: Despite the progress made in understanding the biology of autism spectrum disorder (ASD), effective biological interventions for the core symptoms remain elusive. Because of the etiological hetero- geneity of ASD, identification of a “one-size-fits-all” treatment approach will likely continue to be chal- lenging. A meeting was convened at the University of Missouri and the Thompson Center to discuss strategies for stratifying patients with ASD for the purpose of moving toward precision medicine. The “white paper” presented here articulates the challenges involved and provides suggestions for future solutions. (J Dev Behav Pediatr 37:659–673, 2016) Index terms: autism, biomarkers, precision medicine. Significant progress has been made in understanding Phase II clinical trials.5 This perceived “failure” is likely the biology of autism spectrum disorder (ASD) over the due to the etiological heterogeneity of the subjects with past decade.

Autism Diagnosis Differentiates Neurophysiological Responses To
Tye et al. Journal of Neurodevelopmental Disorders (2015) 7:33 DOI 10.1186/s11689-015-9129-2 RESEARCH Open Access Autism diagnosis differentiates neurophysiological responses to faces in adults with tuberous sclerosis complex Charlotte Tye1,2*, Teresa Farroni3,4, Ágnes Volein4, Evelyne Mercure5, Leslie Tucker4, Mark H. Johnson4 and Patrick F. Bolton1,2 Abstract Background: Autism spectrum disorder (ASD) is a common and highly heritable neurodevelopmental disorder that is likely to be the outcome of complex aetiological mechanisms. One strategy to provide insight is to study ASD within tuberous sclerosis complex (TSC), a rare disorder with a high incidence of ASD, but for which the genetic cause is determined. Individuals with ASD consistently demonstrate face processing impairments, but these have not been examined in adults with TSC using event-related potentials (ERPs) that are able to capture distinct temporal stages of processing. Methods: For adults with TSC (n = 14), 6 of which had a diagnosis of ASD, and control adults (n = 13) passively viewed upright and inverted human faces with direct or averted gaze, with concurrent EEG recording. Amplitude and latency of the P1 and N170 ERPs were measured. Results: Individuals with TSC + ASD exhibited longer N170 latencies to faces compared to typical adults. Typical adults and adults with TSC-only exhibited longer N170 latency to inverted versus upright faces, whereas individuals with TSC + ASD did not show latency differences according to face orientation. In addition, individuals with TSC + ASD showed increased N170 latency to averted compared to direct gaze, which was not demonstrated in typical adults. A reduced lateralization was shown for the TSC + ASD groups on P1 and N170 amplitude. -
Sleep As a Translationally-Relevant Endpoint in Studies of Autism Spectrum Disorder (ASD)
www.nature.com/npp NEUROPSYCHOPHARMACOLOGY REVIEWS Sleep as a translationally-relevant endpoint in studies of autism spectrum disorder (ASD) Galen Missig 1, Christopher J. McDougle2,3 and William A. Carlezon Jr.1 Sleep has numerous advantages for aligning clinical and preclinical (basic neuroscience) studies of neuropsychiatric illness. Sleep has high translational relevance, because the same endpoints can be studied in humans and laboratory animals. In addition, sleep experiments are conducive to continuous data collection over long periods (hours/days/weeks) and can be based on highly objective neurophysiological measures. Here, we provide a translationally-oriented review on what is currently known about sleep in the context of autism spectrum disorder (ASD), including ASD-related conditions, thought to have genetic, environmental, or mixed etiologies. In humans, ASD is frequently associated with comorbid medical conditions including sleep disorders. Animal models used in the study of ASD frequently recapitulate dysregulation of sleep and biological (diurnal, circadian) rhythms, suggesting common pathophysiologies across species. As our understanding of the neurobiology of ASD and sleep each become more refined, it is conceivable that sleep-derived metrics may offer more powerful biomarkers of altered neurophysiology in ASD than the behavioral tests currently used in humans or lab animals. As such, the study of sleep in animal models for ASD may enable fundamentally new insights on the condition and represent a basis for strategies that enable the development of more effective therapeutics.

PRACTICE PARAMETER FOR THE ASSESSMENT AND TREATMENT OF CHILDREN AND ADOLESCENTS WITH AUTISM SPECTRUM DISORDER ABSTRACT Autism spectrum disorder (ASD) is characterized by patterns of delay and deviance in the development of social, communicative, and cognitive skills which arise in the first years of life. Although frequently associated with intellectual disability, this condition is distinctive in terms of its course, impact, and treatment. ASD has a wide range of syndrome expression and its management presents particular challenges for clinicians. Individuals with an ASD can present for clinical care at any point in development. The multiple developmental and behavioral problems associated with this condition necessitate multidisciplinary care, coordination of services, and advocacy for individuals and their families. Early, sustained intervention and the use of multiple treatment modalities are indicated. Key Words: autism, practice parameters, guidelines, developmental disorders, pervasive developmental disorders.

Sensory Processing Disorder and Occupational Therapy
Running head: SENSORY PROCESSING DISORDER AND OCCUPATIONAL 1 Sensory Processing Disorder and Occupational Therapy (Persuasive Essay) ENGL 2201 East Carolina University SENSORY PROCESSING DISORDER AND OCCUPATIONAL THERAPY 2 Sensory Processing Disorder is a condition that causes hyposensitivity and hypersensitivity among its victims. Many people who suffer from Sensory Processing Disorder (SPD) also have other disabilities such as autism, ADHD, and other cognitive disorders. According to The Professional Counselor, approximately 5-17% of the population has symptoms of SPD (Goodman-Scott & Lambert, 2015. p. 274). There has been an ongoing debate among medical professionals on whether SPD should be considered its own disorder. Currently in the DSM-V, SPD is not classified as its own disorder because these symptoms are often accompanied by other cognitive disorders. Even though SPD is not in the DSM-V it is still imperative that these individuals seek treatment for their symptoms. For the last 50 years, occupational therapists have been studying this disorder, and formulating treatment plans to help relieve symptoms (Goodman-Scott, & Lambert, 2015. p. 274). Occupational therapists goal is to improve a patient’s quality of life by using individualized, evidence based treatment plans. According to the American Academy of Pediatrics, occupational therapy is considered the main form of treatment for symptoms of SPD because it is noted in the DSM-V as a symptom of autism (Critz, Blake, & Nogueira, 2015. p. 711). Some of the treatment plans occupational therapists use to relieve symptoms of SPD among their patients are sensory integration programs, sensory diets, floortime therapy, and self-management programs. This article argues for the effectiveness of the treatment methods implemented by occupational therapists on individuals with symptoms of SPD. -

Better Models for Brain Disease NEWS FEATURE Traditional Animal Models Have Had Limited Success Mimicking Mental Illnesses
NEWS FEATURE Better models for brain disease NEWS FEATURE Traditional animal models have had limited success mimicking mental illnesses. Emerging technologies offer the potential for a major model upgrade. Helen H. Shen, Science Writer Starting with just a tiny chunk of skin, neuroscientist Flora Vaccarino tries to unlock mysteries hidden inside the brains of people with autism. By introducing certain genes to the skin cells, the Yale University School of Medicine researcher reprograms them to an embryo-like state, turning them into induced plu- ripotent stem cells (iPSCs); and with two more months of nurturing and tinkering, Vaccarino can guide the cells to develop into small balls of neural tissue akin to miniature human brains. Less than two millimeters across, these “cerebral organoids” don’t look or work exactly like full brains. But they contain many of the same cell types and un- dergo some of the same key developmental pro- cesses as fetal brains. Also key, the cells perfectly match the genetic makeup of the adults and children with autism who donated the original skin samples, allowing Vaccarino’s team to track the very beginnings of their disorder. Human brain tissue usually can’t be collected and studied until after death, and by then, it can be too late to glean important insights. “You don’t get to see the same person’s cells progressing through a series of steps and time points, like we do with these organo- ids,” Vaccarino explains. “The organoids are a very powerful system. You can actually change things and see what the outcome is going to be.” Neurons such as these, derived from the induced pluripotent stem cells of a Parkinson’s Predicting outcomes and, crucially, developing disease patient, are on the forefront of efforts to improve models for brain disease.
